Problems solved by technology

Furthermore, according to prior art manufacturing methods, the amount of antimicrobial agent is limited to low levels (e.g. less than 1% by weight) in order not to impair the physical properties of the glove
As a result, the antimicrobial will diminish soon after glove use as the antimicrobial gradually disappears from the glove surface and cannot be replenished

Embodiment 1

[0052] 1 g of the dye of Chemical Formula 1 was dissolved in 400 ml of water. 100 g of PVC powder were added with stirring. After 1 hour, the dye solid was filtered off. Dyed PVC (80 g) was added to a further 320 g of PVC powder and 260 g of dioctyl titanate was added. 130 g of DN300 diluent (CAS: 6846-50-0 from DYNAMIC CHEMICAL BINHAI INDUSTRY Co., Ltd.) was added, and the mixture was stirred for 1 hour. The glove mold was immersed in the liquid and dried in an oven at 180 °C for 3 minutes.

[0053] The membrane is transparent and analyzed by uv-vis in a Hach-DR3900 spectrophotometer by placing the membrane in the light path and running the spectrum in absorbance mode from 400nm to 800nm ​​at 5nm intervals, which shows that the dye mainly Exist in monomeric form (the absorption at 680nm is the monomeric form of the dye). The peak at 680nm is monomeric and the peak at 640nm is from the aggregated form of phthalocyanine.

Abstract

A formulation for manufacturing an antimicrobial article, the formulation comprising: 25 to 75 parts by weight of a PVC resin; 20 to 40 parts by weight of a plasticizer; 10 to 30 parts by weight of a solvent diluent; 0.001 to 1% by weight, preferably 0.001 to 0.3% by weight, of a singlet oxygen-producing dye.

Description

technical field [0001] The present invention relates to formulations and methods for making antimicrobial articles, and more particularly to formulations and methods for making antimicrobial gloves. Background technique [0002] Protective gloves are widely used in hospitals, pharmaceutical factories, food factories, kitchens or even public places. Gloves are usually made of polymer resins. For example, so-called vinyl gloves are produced by using polyvinyl chloride (PVC) as a main component. [0003] Conventionally, the use of protective gloves isolates germs from the user's hands to reduce the risk of bacterial infection. Since bacteria attached to the glove surface are not killed, bacteria or other microorganisms may grow on the glove surface. Therefore, gloves may become a new source of infection. [0004] It is desirable to provide continuous bacterial protection during the use of the glove. To achieve continuous bacterial protection, antimicrobial gloves were deve...
